Can anyone , ? -1.3 ≥ 2.9 -0.6r graph the solution

Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one.   Adding 0.6r to both sides makes the coeff. of r a positive one:   0.6r greater than or equal to 2.9+1.3.

0.6r then is equal to or greater than 4.2.  Divide both sides by 0.6 to isolate r:

r greater than or equal to 7.

Let r be represented by the horizontal number line.  Darken r = 7 and also darken the r axis to the right of r=7.

Idon't know the answer
